I have one more patch for you to try. Attached at the end. Hopefully it will confirm the root problem.

ACPI 6.4 Could not convert 1 to 4 panic
For a new project, we are trying a Lenovo Thinkstation M70s Gen 3 running OpenBSD. We hit a hurdle straight up when validating the hardware, the kernel doesn't get past the ACPI initialisation. Specifically: acpi0: at bios0: ACPI 6.4Could not convert 1 to 4 panic: aml_die aml_convert:2095 The operating system has halted. Please press any key to reboot. Whole kernel banner can be seen here: https://pbs.twimg.com/media/Ff8ilONakAMI6gQ?format=jpg Running 7.2-current (20221024) Sorry, there isn't much extra information I can give. The usual secure boot is off. FWIW, the machine was shipped from Lenovo with Ubuntu pre-installed. Thanks, Jason.
7.2: tsc timecounter running too fast on ESXi 7.5
I'm one of several people experiencing this issue with OpenBSD 7.2 on VMware ESXi 7.5.

Re: Had to set 'kern.timecounter.hardware' to 'acpitimer0' to fix system clock going too fast

The only major thing that changed in the frequency calibration code between 7.1 and 7.2 is the introduction of additional delay(9) implementations. Let's see if removing them from the picture changes the result we get. Can you compile and boot a -current kernel with the attached patch and send the resulting dmesg? Patch has fixed the issue!

Do not enable TSO on forwading infrastructure. It is only useful on servers and clients. And even then receive TCP segment offloading does not scale on systems handling many concurrent TCP sessions. The cards just don't have enough RAM to reassemble that many streams. So I'm not surprised that some connections show strange behaviour. -- :wq Claudio
packet forwarding issues with TSO
Hi @bugs, I've a pair of boxes peering bgp with isp infrastructure and on premises infrastructure One of the routers was upgraded to 7.2 last night without any issues. This is a 'border router' announcing private prefixes via bgp to isp equipment and customer on a vpn that is pushing ~5tb a day. (upload and download aggregated) It has a few rules on pf.conf setup with sloppy state. (only one router was upgraded, the traffic flow is assymetric) After upgrading, TSO was enabled on this NICs using ifconfig ix0 tso; ifconfig ix1 tso. It was not possible to detect any issues on the maintenance window, yet today with more users using the network we had reports of issues. Some traffic would be very *slow*, some traffic would flow normally. After disabling TSO, the packet forwarding resumed its normal state. Unfortunately I do not have pcaps to support this issue. The router is running 7.2 with latest patches available Please let me know what further information would be useful in this scenario.
